Title: Explosive welding of hollow metal cylinders  such as pipes
IPC: B23K20/08
Filed: 1973-03-20
Abstract: 1430141 Welding by pressure EXXON RESEARCH & ENG CO 20 March 1973 [12 May 1972] 13233/73 Heading B3R An apparatus for use in the explosive welding of the ends of hollow metal cylinders comprises an annular metal collar to be welded about the abutting ends of the hollow cylinders which collar has a maximum radial cross-sectional thickness at least at its central diametral plane and a minimum radial cross-sectional thickness in the diametral planes at its ends and its inner surface is divergent towards each end of the collar so that when arranged on the cylinders annular spaces increasing in width towards the ends of the collar are provided, explosive material is located on the outer surface of the collar and means are provided for simultaneously detonating the explosive material at two or more equiangularly spaced initiation points in the central diametral plane of the collar. In an embodiment a mandrel 11 is arranged within two abutted pipes 40, 40a, Fig. 9, and the mandrel is expanded into tight contact with the abutting pipe ends. The mandrel comprises four interengaging wedge segments 12, 13, 14, 15, Figs. 1, 3, arranged about two telescoping members 41, 42 extending respectively from plates 22, 25. A rotatable threaded rod 26 engages in a nut 27 secured to plate 22 and is connected to plate 25 by lock nuts 28, 29 to allow rotation relative thereto and resilient pads 30, 31 are provided between the segments 12, 14 and plate 22 and pads 32 between segments 13, 15 and plate 25. Rods 16, 16<SP>1</SP>, 17, 17<SP>1</SP>, 18, 18<SP>1</SP>, 19, 191 extend from each end of each segment. The expansion of the mandrel is effected by rotating the rod 26 to draw the plates 22, 25 together, involving compression of the pads. A collar 46 with cylindrical outer surface and tapered inner surfaces and carrying layers of explosive 46 is arranged about the abutting ends and then the rod 26 is rotated in the opposite direction to release the plates 22, 25, the segments remaining wedged in contact. A number of strips of explosive are arranged on an annular body 47 in contact with the explosive 46 at spaced points and are simultaneously initiated. During detonation of the explosive the collar is formed into welding contact with the pipe ends and the mandrel segments are released by the explosive forces. The collar may, in a modification, have an inward curvature in its outer surface, a portion of the inner surface being cylindrical which may be long enough to cover a V recess formed between the pipe ends. A metal or other ring may be placed in the recess. The explosive may be moulded or cast.

Title: Process of producing antirachitically active preparations
IPC: A61K31/593
Filed: 1936-05-13
Abstract: Antirachitic preparations having special efficacy for chickens are obtained by extracting the fatty matter of invertebrate animals (other than members of the family Helicidae), the sterol fraction of which contains a provitamin-D sterol to the extent of at least 0,25 per cent, removing the unsaponifiable fraction and irradiating it with ultraviolet light.  Invertebrates of the following classes or phyla are treated in the manner described examples of each being given: Porifera (sponges), ichinodermata (starfish), annelida (earthworm, leech), mollusca (slug, oyster, whelk, squid), arthropoda (lobster, mealworm, locust, pupa of silkworm, bee).  According to a suitable method of preparation the raw material is comminuted, if desired with sand, sodium sulphate, alcohol or acetone, and dried in vacuo.  The fat is then extracted with solvents such as ether or petrol-ether, halogen containing solvents being preferably avoided. The fat is saponified in usual manner, e.g. by alcoholic soda or potash, the soap solution being freed from part of the alcohol by distillation and the unsaponifiable fraction separated by dilution with water and extracting or by precipitating lime soaps by treating with a lime salt and extracting the unsaponifiable constituents precipitated with the lime soaps.  The sterol fraction may be purified by recrystallization from alcohol and methyl alcohol. Reference has been directed by the Comptroller to Specification 236,197,* [Class 2 (iii)].

Title: Improvements in the sulphonation of aromatic amines
IPC: C07C309/45
Filed: 1930-05-02
Abstract: Aminosulphonic acids are formed by mixing an aromatic amine with a high-boiling organic liquid medium which is not preferably attacked by sulphuric acid and chemically indifferent towards the amine, adding with agitation sulphuric acid to give the acid sulphate of the amine and heating the suspension of the acid sulphate so obtained to a temperature at which conversion to the amine sulphonic acid takes place.  It is essential that the water be removed as it is formed and the pressure may be lowered to expedite the distillation of the water.  In general amines, such as aniline, the toluidines, xylidines, chloranilines, or a - or b -naphthylamine, which give sulphonic acids by the "baking" process are suitable amines for the present process.  Suitable high-boiling liquids are chlorbenzene, tetrachlorethane, solvent naphtha, xylene, or the petroleum fractions known as "white spirit" or "kerosene" or those of a higher boiling-point known as "transformer oil."  In examples a -naphthylamine or aniline is sulphonated in "white spirit" under normal pressure and a -naphthylamine sulphonated in "transformer oil" under reduced pressure.
